Title: Carbon-containing odor controlling compositions.
Inventor: KARAPASHA NANCY
IPC: A61F13/15
Filed: 1991-01-31
Abstract: Compositions comprise carbon particles combined with white odor-controlling agents by means of binders. The preferred particle form of the compositions is substantially lighter in color than the original carbon, and the resulting particles are preferred for use in the manufacture of catamenials, diapers, bandages, and the like. Particles comprising carbon and zeolites are not only desirably lighter in color, but also control a broad spectrum of malodors associated with body fluids.

Title: Cylinder lock.
Inventor: PEDERSEN KAI
IPC: E05B27/04
Filed: 1991-03-08
Abstract: Cylinder lock comprising a plug (1) having a key channel (2), a housing (3) surrounding the plug and a number of bores (11-17) in the plug and the housing for divided locking pins (21) adapted to be shifted in their longitudinal direction in the bores by means of a key inserted in the key channel (2). An intermediate sleeve (5) is provided between the plug (1) and the housing (3), and is adapted to be rotated about the same axis (10) as the plug. The sleeve (5) has bores corresponding to the bores (11-17) in the housing, for through-going locking pins (21). The locking pins are divided for establishing shear surfaces both between the plug (1) and the sleeve (5) and between the sleeve (5) and the housing (3), upon insertion of a correct key. An additional bore (19) for an auxiliary pin (20) is provided in the housing (3) and the sleeve (5) and adapted to be engaged by surfaces (1A, 1B) on the plug (1), so that the blocking effect of the auxiliary pin with respect to the sleeve (5) in relation to the housing (3), is removed when the plug (1) is rotated through a given angle in relation to the sleeve. Drive means (7, 9) are adapted to transfer the rotation of the plug beyond said given angle, into movement of a blocking member in a lock, for example a locking bolt.

Abstract: La présente invention décrit un procédé de fabrication de rutile synthétique à partir de minerai titanifère ou de concentré. La fabrication s'effectue en trois étapes, à savoir réduction, élimination du fer par lessivage ou aération, et élimination des autres impuretés par lessivage dans une solution d'acide inorganique fort, par exemple acide chlorhydrique ou sulfurique. Les conditions de la réduction sont contrôlées jusqu'à obtention de fer métallique, d'une phase principale de production de rutile, et d'une phase mineure de production d'impuretés. Ces dernières peuvent consister en métatitanate, anosovite, ou pseudobrookite. On préférera en général parvenir à la formation de métatitanate. Les agents de réduction adéquats comprennent des matériaux carbonés ou des gaz hydrogénés, par exemple gaz naturel ou gaz synthétique. Ce procédé permet d'éliminer plus de 80 % du contenu en magnésium, fer, et manganèse demeuré à l'état d'oxydes après la réduction, ainsi qu'une partie substantielle de la teneur en aluminium.

Abstract: Les capacités d'une paire de condensateurs associés à un réseau neuronal sont agencées pour être complémentaires en valeur, même lorsque leur capacité différentielle est soumise à des variations, de manière que la somme des capacités reste égale à une constante Ck. Chaque condensateur d'un ensemble de condensateurs constitutif présentant des capacités corrélées en fonction de puissances de deux est sélectionné pour être un constituant de l'une ou de l'autre paire de condensateurs, la sélection étant effectuée par des transistors à effet de champ (FET) faisant office de portes de transmission. Les signaux de porte destinés au FET sont des éléments respectifs des bits se trouvant dans un nombre binaire stocké dans un élément de stokage de mots d'une mémoire à semi-conducteurs.

Abstract: L'invention concerne un laser (10) qui est capable de produire de la lumière à partir d'un ensemble de fréquences choisi qu'on ne peut obtenir en utilisant un laser employant un seul gaz. Ledit laser (10) peut produire des longueurs d'ondes lumineuses choisies et bien définies. Le laser (10) peut également éliminer les fréquences indésirables afin d'empêcher de telles fréquences de prendre de l'énergie provenant des longueurs d'ondes voulues. Le laser (10) forme un laser à plusieurs gaz; on utilise un mélange d'argon et de krypton. L'argon est connu pour produire un rayon laser de couleur bleue de bonne qualité dans la zone de 438 nm. L'argon est mélangé à du krypton qui produit également un faisceau de couleur bleue à 482 nm et 476 nm. En outre, le krypton produit des faisceaux de forte intensité dans les longueurs d'ondes du rouge, du jaune et du vert (respectivement à 647 nm, 568 nm et 529 nm). L'accès à chacune de ces couleurs est assuré par l'argon et le krypton présents dans le mélange. Certaines fréquences lumineuses sont inutiles et indésirables. On peut éliminer les longueurs d'ondes indésirables principalement à l'aide des systèmes optiques qu'on utilise. Les systèmes optiques (18, 20) choisis sont ceux qui transmettent les longueurs d'ondes indésirables. Il en résulte qu'aucun effet laser n'a lieu au niveau des longueurs d'ondes indésirables.

Title: A scalable parallel vector computer system.
Inventor: OBERLIN STEVEN M
IPC: G06F15/167
Filed: 1991-10-04
Abstract: The specification discloses a scalable parallel vector computer system including a multiple vector processor network, a common memory, and communication network for communicating between the vector processors and the common memory. The communication network is designed such that information transmitted suffers variable latencies. These latencies are substantially hidden through the use of context switching vector processors containing multiple instruction threads. These vector processors execute the instructions in one thread until an issue block is encountered, then context switch to the next thread, continuing this process until all instructions are executed. This context switching significantly reduces processor idle time. As a result, the system of the present invention may be scaled to virtually any number of processors by simple replication without substantially impacting individual processor performance.

Abstract: In an axial flow gas turbine engine, a scavenge air removal and bypass system and method of operation that reduces the operational pressure of a lube oil system is provided. An air-oil mixture is created by a mixing action of lube oil and air in bearings, seals, and gears located in various parts of a gas turbine engine which is collected by one or more sumps located throughout the lube oil system. Scavenge pumps (45) transfer the air-oil mixture to an air-oil separator (50) where solid oil (70) ischarge air (95) are returned to a lube oil tank (22) through separate lines. The discharge air pressurizes the lube oil system to accomplish normal operation. By providing separate return lines for the solid oil and the discharge air, the lube oil system pressure required to operate is reduced.
